You're on the right track, Roid. You're just impatient.
Keep building on those positive interactions but don't force anything. Keep on being friendly and cordial, no R talk.
I remember my goal was to make it safe for WAW to talk to me. I kept being friendly but not over the top. Very slowly these conversations evolved into deeper and more meaningful things. Eventually we started talking about "us" without any pressure.
It takes time, allow her to feel safe with you. Baby steps.
